All checks were successful
CI / lint-and-test (push) Successful in 24s
- Removed the ability to specify multiple event types in the ICS calendar generation API, ensuring it only returns duty shifts. - Updated the associated test to reflect the change in behavior, confirming that unknown query parameters are ignored. - Revised documentation to clarify the API's focus on duty shifts only, enhancing clarity for users.
